Solenoid Valve Fundamentals
A solenoid valve is an electromechanically operated valve that controls the movement of liquids or gasses. It consists of a solenoid (an electrical coil) and a valve physique. When an electrical present passes via the solenoid, it generates a magnetic discipline that actuates the valve, both opening or closing it. This mechanism permits for exact management over fluid movement, making solenoid valves important in automated methods.
Forms of Solenoid Valves
Based mostly on Actuation State
- Usually Closed (NC) Solenoid Valves: Of their default state, these valves stay closed. They open when an electrical present is utilized, permitting fluid to move via. NC valves are generally utilized in purposes the place the default state ought to stop fluid movement.
- Usually Open (NO) Solenoid Valves: These valves stay open of their default state and shut when an electrical present is utilized. NO valves are utilized in purposes the place the default state ought to enable fluid movement.
- Bistable (Latching) Solenoid Valves: These valves keep their state (open or closed) even when the ability is eliminated. They solely require a pulse of electrical energy to alter states, making them energy-efficient and appropriate for purposes the place energy conservation is crucial.
Based mostly on Circuit Perform
- Two-Means Solenoid Valves: These valves have two ports and may both enable or block the movement of fluid. They’re utilized in easy on/off management purposes.
- Three-Means Solenoid Valves: These valves have three ports and may direct the movement between two completely different paths. They’re utilized in purposes requiring the diversion of movement or mixing of fluids.
- 4-Means Solenoid Valves: These valves have 4 ports and are utilized in advanced methods the place a number of movement paths have to be managed. They’re generally utilized in pneumatic and hydraulic methods.
